When the front torus shaped airbag 3 shown in fig. 12 and 13 is inflated, the inflated state of the front torus shaped airbag 3 is as shown in fig. 14 and 15.
The material of the annular air bag is preferably silica gel, the friction coefficient between the annular air bag and metal is large, stable support can be provided, and the silica gel is excellent in ductility and convenient to prepare.
When the first rear motor 10, the second rear motor 11 and the first front motor 12 work simultaneously to drive the first rear reel 13, the second rear reel 14 and the first front reel 15 to rotate simultaneously to take up the wire, the first driving wire 7, the second driving wire 8 and the third driving wire 9 are pulled simultaneously, the spring 6 is compressed, and the whole robot contracts. When the robot is contracted, the first rear motor 10, the second rear motor 11, and the first front motor 12 are simultaneously operated to rotate the first rear reel 13, the second rear reel 14, and the first front reel 15 simultaneously to perform a line-feeding operation, and the springs 6 are extended to extend the robot. When one of the first driving wire 7, the second driving wire 8 and the third driving wire 9 is pulled and taken up, the robot can turn and bend to one side.
The supporting part of the whole robot mainly utilizes the friction force between the air bag and the inner wall of the pipeline to complete the positioning task of the robot. In the process of detecting the pipeline and the valve, the front annular air bag 3 and the rear annular air bag 4 are respectively inflated by an external air pump through the first hose 23 and the second hose 24, the air bags are in contact with the inner walls of the pipeline and the valve to generate pressure after being expanded, and the head or the tail of the robot is fixed relative to the inner walls through the generated friction force, so that the pose of the robot can be conveniently adjusted. The size of the air bag can be adjusted through the air pump, so that the robot can be fixed on pipelines with different diameters, and the fixation of the pipeline with the variable diameter of the valve is realized. Therefore, the following describes the robot crawling process according to different scenarios:
in the first scenario, the valve shown in fig. 16 is taken as an example, and the crawling and positioning processes are as follows:
(1) inflating the front circular airbag 3, expanding the front circular airbag 3, and fixing the head of the robot (namely, a part of the expanded front circular airbag 3 is attached to the inner wall of the pipeline or the whole circle of the expanded front circular airbag 3 is attached to the inner wall of the pipeline) as shown in fig. 17 and 18, wherein the rear circular airbag 4 is in a contracted state;
(2) the first rear motor 10, the second rear motor 11 and the first front motor 12 act simultaneously to take up wires, the spring 6 is compressed, as shown in fig. 19, the rear circular air bag 4 moves forwards, and the whole robot is shortened;
(3) as shown in fig. 20, the rear circular airbag 4 is inflated to fix the tail of the robot (i.e. a part of the expanded rear circular airbag 4 is attached to the inner wall of the pipeline or the whole circle of the expanded rear circular airbag 4 is attached to the inner wall of the pipeline), the front circular airbag 3 is deflated to shrink the front circular airbag 3, the first rear motor 10, the second rear motor 11 and the first front motor 12 act to perform a paying-off operation, the spring 6 is extended, the front circular airbag 3 moves forward, and the whole robot is extended;
(4) as shown in fig. 21, after the robot turns around in the valve, the front circular airbag 3 is inflated to expand, the front circular airbag 3 is positioned, the first rear motor 10, the second rear motor 11 and the first front motor 12 act simultaneously to take up the wire, and the rear circular airbag 4 moves forward.
As shown in fig. 22 and 23, when the robot continues to move forward to another section of the pipeline of the valve, the front circular air bag 3 is inflated to expand, and the front circular air bag 3 completes positioning.
The pipeline in the valve is usually in a special-shaped drift diameter, the inner diameters of the pipelines are not consistent, and the robot can be completely suitable for the special-shaped drift diameter.
The second scenario, as shown in fig. 24, works on a plane, and the positioning and crawling process is as follows:
(1) as shown in fig. 24 (a), in an initial state, the spring 6 is in a compressed state, the front circular airbag 3 is inflated, the front circular airbag 3 expands, the friction force between the front circular airbag 3 and the plane is reduced, the friction force between the taper angle of the rear circular airbag 4 and the plane is larger, and the rear circular airbag 4 is positioned and fixed on the plane;
(2) as shown in (b), the first rear motor 10, the second rear motor 11 and the first front motor 12 act simultaneously to perform a wire releasing operation, the spring 6 extends, the rear circular airbag 4 slightly shifts backwards, the taper angle of the rear circular airbag 4 in (b) is slightly deformed, the friction force is increased, the front circular airbag 3 moves forwards, and the robot becomes long as a whole;
(3) as shown in the figure (c), the front circular air bag 3 is deflated to shrink (the friction force between the taper angle of the front circular air bag 3 and the plane is increased), and the rear circular air bag 4 is inflated to expand (the friction force is reduced without the taper angle action);
(4) as shown in the figure (d), the first rear motor 10, the second rear motor 11 and the first front motor 12 act to take up wires, the spring 6 is compressed, the taper angle of the rear circular air bag 4 in the figure (d) is slightly deformed, the friction force is increased, the rear circular air bag 4 moves forwards, and the whole robot is shortened;
(5) as shown in figure (e), the front torus shaped bladder 3 is inflated to expand it, and the rear torus shaped bladder 4 is deflated to contract it, starting the next cycle.
And the third scene works on the arc-shaped inner wall of the tank-shaped container, and the working mode is the same as that of the second scene.
The first rear motor 10 and the second rear motor 11 are respectively positioned on the front and the rear surfaces of the rear circular base 2, and the first front motor 12 is positioned on the front circular base, so that the overall diameter of the robot is smaller, and the robot is beneficial to miniaturization design.
The invention has the advantages of ingenious structure and high flexibility, and the soft trunk with the spring type wire drive can realize the large-range bending and stretching of the robot space and complete the detection task of complex environment.
It should be noted that the front circular air bag 3 and the rear circular air bag 4 may not be provided with cone angle structures, and may also crawl in pipelines and valves. As shown in fig. 25 and 26, the front and rear circular airbags 3 and 4 are replaced with front and rear circular airbags 25 and 26 having no taper angle structure.
In order to make the front circular air bag 3 and the rear circular air bag 4 adapt to pipelines with larger inner diameter sizes, the front circular air bag 3 and the rear circular air bag 4 are optimized and improved. The air cavity of the front circular air bag 3 is provided with a plurality of reinforcing ribs 3-3, the structure of the front circular air bag provided with the plurality of reinforcing ribs is shown in figures 27-30, and the air bag is in a contraction state. When the air cavity of the front circular air bag is inflated, the expanded state is shown in figures 32-38, three groups of reinforcing rib arrays are shown in the figures, each group of reinforcing rib array is composed of a plurality of reinforcing ribs 3-3, each reinforcing rib 3-3 is connected in the air cavity along the axial direction, one end of each reinforcing rib 3-3 is connected with the left inner wall of the air cavity, and the other end of each reinforcing rib 3-3 is connected with the right inner wall of the air cavity (when the air bag is prepared by using a silica gel material through a pouring process, the reinforcing ribs 3-3 are wrapped by silica gel to form wrapping layers 3-4, and the wrapping layers 3-4 are integrally formed with the air bag body). The material of the reinforcing ribs 3-3 can be plastic.
